Ŷ If the spark arrestor or work rest becomes worn or
damaged, replace it with an identical replacement from
the authorised service centre.
Ŷ When fitting a new grinding wheel, always check that
the stated maximum RPM meets or exceeds that stated
on the grinder sander. Ensure the wheel diameter and
arbor size meet that stated on the specifications. Also
check the new wheel for damage, such as flaws or
cracks.
Ŷ Do not use sanding belt larger than needed.
Ŷ Make sure the sanding belt is installed in the correct
direction.
Ŷ Do not operate the product without a properly tracked

product.
Ŷ Change the sanding belt frequently to maintain the
product’s ability to effectively remove material.
Ŷ Do not use a sanding belt which is damaged, torn, or
loose. Use only a sanding belt of the correct size.
Ŷ Choose a belt of the correct size and appropriate
roughness for the task. Use belts with a lower grit
number for removing more material, higher grit number
for removing less material and for a finer finish. Replace
the belt if it becomes damaged, clogged with debris or
is worn.
Ŷ Do not force the product. Use the correct product for

Ŷ Never grind or sand more than one workpiece at a time.
Do not stack more than one workpiece on the work rest
at a time.
Ŷ Do not reach into the product while it is running.
Ŷ Avoid awkward operations and hand positions where
a sudden slip could cause your hand to move into the
grinding wheel or sanding belt.
Ŷ Avoid kickback by grinding or sanding in accordance
with directional arrows.
Ŷ Never stand or have any part of your body in line with
the path of the workpiece.
Ŷ Chips and splinters must not be removed while the
product is running.
Ŷ The dust produced when using the product may be
harmful to health. Do not inhale the dust. Use a dust
absorption system and wear a suitable dust protection

marked speed equal or greater to that marked on the
machine.
Ŷ Never use grinding wheel that is too thick to allow outer
flange to engage with the flats on the spindle. Larger
wheels will come in contact with the wheel guards,
while thicker wheels will prevent the bolt from securing
the wheel on the spindle. Either of these situations
could result in a serious accident and can cause serious
